R~USABLE STACKABLE TRAY FO~ CANS
BAC~GROUND oY THE 12~EN~OPI
The present invention rela~ to trays tor transpor~ing and
storing containers such as beverage containers, and more par~icularly
Ior those storing two or more sLx-packs o~ pull-top aluminun cans. It
~urther relates to such trays which cal) be securely stac~ed one on top
Or an~ther both when tull and when empty.
Pull-top aluminum cans rOr SOI t ~lnk~;, o~her bsverages and the
like are stored and transported during the clistribultion stage ~ypically
in short-walled card~ard trays or in cardboard boxes. On the other
hand as to bottles, because o~ the ever inereasing cos~ in dispc~sable
tertiary packaging, returrlable, reusable con~alner~ are becoming po~
ular rOr the storage and handllng ot bottles. HoweYer, un~ke plasti~
or glass bottles which have rounded edges on their clown or 1:0p, pull-
top aluminum cans have square sharp corners (as compared with bot-
tle top~) where th~ tOp o~ the can attaches to the s~des thereo~.
Thereiore, partlcular di~lculties have bsen encountered in the stack-
ing and manipulating Or the tra~s o~ cans stacked relative to one
another. In lac~, there a~ no known returnable, reusable trays suit-
ab~e lor supportlng pull-top alumlnum cans and which can, when filled
wlth such can~, be sta~ked securely one on top of another, so that the
top tray ot a stack oi f~lled trays can be easily pulled ol~ and along
the stacl~ withaut being ~ted. In other word~, the trays should be
constructed so that when loaded they can ~e easily pivoted and slid
of ~ ot loaded tra~s beneath ~hem withoult having to be li~ted.

D~TAILED DECRIPl~ION O~ PREFERRED
EMBoDnNENTs OF TH13 INVENTIOP~
Re~errlng to the draw~ngs a reusable, s~ackable tray for eans is
illustrated generally at 20/ and ~ formed by a unitary integral plastic
construction. It compr~es a pair OI end wa~ 22, 24, and a pair of
opposed side walls ~6, 28 wherein the end and side walls ase ~n~egrally
~oined to Iorm ~our rounded corners as shown for example at 30. As ~ ~
seen, the end and slde walls 22, 24, 26, 28 form a rectangular stru¢- ~ .
ture shown generally a~ 32. A floor structure designated generally by
reierence numeial 34 ls positioned within and secure~ to the base of
the rectangular struc~ure 32. The perimeter struc~ure 36 o~ the ~loor
structur~ 34 has lts outer suriaces 37 spaced inward about the entir~
perimeter thereo~ insid0 o~ the inside surracs 38 ot tha rectangular
structure 34 to thereby provide a stepped in design. Thi~ allows one
tray 20 to ba taclced and nested se~urely~ but removablyt wishin
another similar or ldentical empty tray 201 and thereby resist relative
lateral mavement as to the sur~ace 38' o~ the rectangu~ar strueture
34~. This nesting relation i~ best illustrated in Figure 7.
The îloor stru~ture 34, as seen In the drawings, de~lnes a we~
lilce construction which mlnimiz~; ths use o~ the plastic material
thereb~ making the tray 20 llghter and easier to handle and also
reducing tho amount OI the plastlc constru~tioll materlal required. It
turther presents a pleasing and interesting design. The central diYid-
inK struts 42, U thereot extendlng, respec~ively, be~ween the centers
o~ the oppa6ed slde walls 26, 28 and the centers o8 tha opposed end
wall~ 22, 24 ~Ivlds the tloor structure 34 into tour equal cells shown :~
generally at 4B, 48, 50 and 52, and aid in manufac~uring by providlng
tlow channel~ ~or the plasti~ mate~lal rrom th~ polnt or in~e~tion at
the part center to the walls. Each cell then represent_ the s~o~age
spacs ror an inter~onnected six-pack oî beYerag~ ~ans, and in~ludes
six spa~ed ¢ir~ular members such as shown by 54 ln tw~by-three
arrays. Spaced redoubt members such as shown by S6 ar~ posltioned
~n the middl~ or ~our ad~acent c~roeuliar member~ 54. A plurality o~
struts 6uch c shown generally at 58 then lnterconne~ts the cir~ular ~ .
` .'`:`` ~:
~33~31~
members 54, the redoub~ membe~s 5G, and the 71Oor perimeter stru~
ture 36.
The strutS 5~ eomprtse lateral strutS such as shown by 60 which
directly connect laterally ad~acen~ circular m~mbers 5~, longitudln~
struts s~lch as shown at 62 which directly conrlect longitudinally ad~a-
cent circular members S~, and ra~ial stru~ such as shown at 64 which
dlrectly connect ~he sides o~ the redoubt mem~rs 56 ~o the circular
members 5~. For the redoubt members 56 pc~sitioned w~thln the cells
46, 4~, 50 or 52, radial struts 64 extend therethrough, as shown in
Figura 3a, ~or example. In anothe~ and perhaps rnore preferr~
destgn, the radtal struts 64 do not extend through the redoubt mem-
bers, as illu~trated in ~igure 3b. Similasly, the dlviding struts ~21 ~
extend through the redoubt members S6 posltioned between ad~a¢ent
cell3 46, 48, S0 or 52.
Partial side and end engaging redoubt members such ~ shown
at 66, 68, resp~ctlvely, are positioned spaced along the tloor perlme-
ter structure 34t and are shown in elevatlon in Figures 5 and 6. Th~e
partial slde and end engaging redoubt members 66, 68 haYs later~ or
longltudlnal redoub~ struts 70, 72, respectively, extendlng through
them as shown. Additionally, the corners such Is shcwn at 74 o~ the
~loor perime~er structura 34 are rounded and have corner engaging
redoubt mem~ers therea~ such as shown at ~6.
The tops of each o~ th~ strutS 58, redoubt members S~, and
circular membars 5~ all have thelr upper sur~aces de~lning a sm~th
upper plane lllustrated general~y at '~8 on which beYerag~ ca~s ean ~
pOEdtloned~ suppo~ed and easily Slid along without obstruetion for
Insortlng th~ cans Into the tray 20 and removin~ them ~rom it. A
plurallty o~ spaced reinIor~ing pasts suCh as shown at 19, lnter~on-
nect the floor structure 34 with the rec~angular structure 32 by
engaging the tops o~ ad~acent lateral or longitudinal st~utS 60, 62 and
extending up and secured to the inside surIace 38 of th~ rectangular
structure 32. ~ .
The redoubt members 5~ are each ~ormed by a continuous
uprigh~ wall 80 and a redoub~ floor 82 secure~ at ~he bot~om end
~i thereot, as best shown In Figure 10. The redoubt walls 80 are `

confi~ured in a squar~Like shape having roundsd corners 83 and with
the middles 8~ of each ot the sides thereo~ (where the radial s~ruts 64
engage) beinB curved inwardly a sligAt amount. The bottom surfaces
o~ the redoub~ wal~s 81 lie generally in the plane o~ the ~ottom su~
faces of the stru~s 58, the noor perimeter structule 36 and the Cil'CU-
lar members 5~. The redoubt ~loor 82, however, extends below that
plane. The redoubt ~loor 82 has about i~ en~ire bottom perimeter a
bevelled edge 85 which is formed at an angle 86 o~, for example,
twenty-five degrees plus or minw five degrees relative to ~he bottom
plane of the rest of ths floor structure 36. Tl~s angle is appropriate
for the current material and market can de~ign. Howev~r9 this angle
would be adfusted as needed to accommodate di~ferent materials and
can designs.
These small, permanent, spaced redoubt members 56 assist the
trays 20 when ~ull to stack securely upon layer~ Or cans 88 beneath
them, as showD in Figure 8. The cans 88 ar~ tho~e such as ~escribed
earlier herein and have square sharp top corne~s 9û. They a~o ailG
the tray 20 to be twisted or pivoted slightly while staeiced on a similar
layer of cars 88 therebeneath and then slld easily o~f o~ the loaded
tray beneath it. ThiS motlon is bes~ illustrated In Figure 9. Thls
allows a dellvery drlver, ~or example~ to pull of ~ the top tray 20 of
any tall stack without havlng to llft that top tray. In other words, a
loaded tray 20 can be easUy slid o~f the loaded tray ~rectly beneath
it. These redoubt members 56 are also spa~ed evenly relatlva to one
another to con~orm to a twenty-four can cor~iguration. It Is also
withln th~ scope o~ this inventlon ~or tray 20 to be configured and
prop8rtloned diiferently as needed to accommodate d~eren~ num-
beir~, slzes and arrangemenls ol containers.
From the foregolng detisiled descriptlon, 1~ will be evident that
there are a number o~ changeis, adaptation~, and modi~lcation~ og the
presient invention which come withln the province ot those skilled in
the art. However, it is Intended that all such variation~ not depaFting
from the spirit og the Invention be considered as Withifl the scope
thereof ias limi~ed solely by the claims appended hereto.
